【 摘 要 】

Out of greenhouse gases causing global warming, CO2 has the largest direct contribution after industrial revolution. To reduce CO2 concentration, it is essential to collect CO2 in the atmosphere and store it in separate places from the atmosphere. As a method of CO2 capture and fixation, we studied a method using carbonization of wood. Based on the statistics of domestic wood production and import/export, we estimated possible amount of fixed CO2 as 8 to 10% of annually emitted CO2 in Japan. Influence of wood carbonization on CO2 concentration in the atmosphere was also examined based on a prediction model for the atmospheric CO2 concentration.
